Re: Integrating GWT and Hibernate without Gilead?
My project http://code.google.com/p/tocollege-net/ uses a HibernateFilter that I hacked together. I think it's an fine approach in theory, but GWT doesn't make it easy to plug in to the serialization process at the right points so it can be a pain when GWT changes its internals. The code is here: http://github.com/jdwyah/tocollege.net/tree/c9dcdf9c32fbfe9e146c39b3ccee1d9b3169deae/src/main/java/com/apress/progwt/server/gwt That said, if I were to do it again I'd probably do Gilead myself. -Jeff On Feb 27, 2:43 pm, Sumit Chandel sumitchan...@google.com wrote: Hello everyone, A reminder to be respectful, friendly and constructive when posting on the forums.

Re: SEO limitation for Hyperlink
Wow. That's a pretty intense SEO solution. I hope the shadowing thing doesn't bite you, it's definitely a cool attempt. Can't you just tickle your analytics urchin directly? ie http://jdwyah.blogspot.com/2008/05/gwt-and-tickling-your-google-analytics.html In your onLoad() you should just be able to tickle it with the current #anchor if it exists, no? -Jeff On Feb 27, 10:26 am, Nicolas Wetzel wetz...@gmail.com wrote: Hi all, I'm working for a compagny which build a web site broadcasting music based on gwt:www.awdio.com On SEO, we've found some interresting stuff to cope with Ajax specifity : search engine can't have javascript engine so they are not able to retrieve the entire html produced by gwt script (or by other ajax framework script). So each page ie gwt screen can not be indexed by them. Rather than duplicate each page with a hand-made static html page accessible by the noscript tag, we produce them with a java program which launches an SWTBrowser (Eclipse 3.4) with the start url :http://www.awdio.com. The main issue with this approach is that the client program has no means of knowing when the page is fully rendered by the javascript process. In the gwt awdio code we implemented a semaphore (flag) which notifies the SWTBrowser based client of the completion. This semaphore works with a hidden DIV drawing/DIV which is accessible or not in the DOM, i.e the the html content produced contains it. With org.eclipse.swt.browser.Browser.getText() we can retrieve the html content, and test for the presence of the above mentioned flag. To do that the java program listens at the Browser statustext event (org.eclipse.swt.browser.StatusTextListener). Also, when the page is loaded, the program gets the content and looks up at all the internal links a href=# built by the gwt Hyperlink widget. Before storing the html content in a cachable static page, all the '#' are remplaced by a '/' so that the bot will get fully qualified URLs (the crawlers do not handle anchors). Finally, the program follow each links with the SWTBrowser so all the static version of the pages can be produced automaticaly. At last in the awdio server, a front-end servlet detects the user-agent of request and if it's a search engine the static produced page is returned. else the gwt host page is returned. As far as I understand, this might be considered shadowing. But the content seen by the crawler is exactly the same as the one seen by the user (after Javascript execution). In the onModuleLoad of the awdio EntryPoint the right part of the url is parsed to build the corresponding historyToken. So when thewww.awdio.com/eventsis requested on a browser, it react in the same way as if the user clicked on an internal link (#events). Everythink looksfine, but there is still a big issue. If a user copies and pastes one of our URLs on his own site, it will contain the hash sign (e.g. :http://www.awdio.com/#events). Which means that the search engine will not rank pages independently (all pages will be considered as a single one :http://www.awdio.com). We can still add link to this page buttons wherever necessary, but it's not satisfactory. To conclude, it seems that this whole solution solves the AJAX indexing issue, with the very annoying exception of page ranking (due to the #anchor URLs). Maybe Google should start to consider #anchors as having a new meaning for our Web 2.0 generation ? Maybe by considering a specific value of the rel attribute ? (e.g. : A HREF=#mypage rel=ispagelinkMy Page/A) ? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: SmartGWT 1.0b2 Released
Hi Benoit,You can essentially override the transformRequest(DSRequest requeest) of DataSource and read the request parameters like startRow, endRow, sort / filter params and issue your own GWT-RPC call and set the returned data on the DataSource. Several users have asked for such a sample and I'll definitely add it. Its just that other higher priority items and releasing 1.0b2 had taken precedence. I'll post updates when such a sample hits SVN on the SmartGWT forum.

Bug in gwt Grid, Setting Background image
Hi,
I found a bug in gwt grid.
I just set a normal background image:
css code:
.myMainGrid{
background-image: url('http://code.google.com/webtoolkit/
logo-185x175.png');
}
java code:
public class Tester extends Composite {
Grid mainGrid;
public Tester() {
mainGrid = new Grid(10,10);
mainGrid.setWidth(500+px);
mainGrid.setHeight(500+px);
mainGrid.setBorderWidth(1);
initWidget(mainGrid);
setStyleName(myMainGrid);
}
}
entry point code:
public class MyEntryPoint implements EntryPoint {
/**
* This is the entry point method.
*/
public void onModuleLoad() {
DialogBox dlgMainScreen = new DialogBox();
dlgMainScreen.setText(test );
dlgMainScreen.add(new Tester());
dlgMainScreen.show();
dlgMainScreen.center();
}
}
Here is my screenshot:
www.freewebtown.com/salvindata/data/gwt%20background%20bug.JPG
What is undesirable is that every cell in First Column gets the same
image as background. i tried same css
in a simple html table and i found it works fine. why does gwt do so ?

Re: How to create listbox with nothing selected by default?
Hello Dave, I have a similar issue with you. Not exactly the same but I think it is much related. On IE and Hosted (on all other browsers it is working properly) even if I do SetVisibleItemCount = 18 I will see only a small listbox with place to see only the first element of the list (the same height with a textbox). How did you overcome this? From your description I understand you went one step further and you discovered a new bug in the same area of GWT ( listbox + setVisibleCount + IE/Hosted).

I found another post suggesting setting the selected index to -1, then programatically unsetting the previously selected item setItemSelected(index, false), but that doesn't work for me either.

[gwt-contrib] RemoteServiceServlet
So just a quick proposal: Remove the private on writeResponse and make it protected. I understand that ProcessCall is package default, but it is causing me problems with my current effort. What I want to do is take a large, but slow, build process and have it Comet stream responses to a single method call on an RPC service that implement StreamServiceIterator back out. I can do this by clobbering the processCall() method, the problem is, if I monkey with the Response output stream at that point, writeResonse() is always going to throw exceptions (outputstream closed). However, because I am wanting to stream data from a network read, rather than read it all into the server RAM, waiting for writeResponse() to get called is unacceptable. If I could just do this in the processCall() and make writeResponse() silently do nothing, that would be ideal. --~--~-~--~~~---~--~~ http://groups.google.com/group/Google-Web-Toolkit-Contributors -~--~~~~--~~--~--~---
